RESUMEN
Objective:To discuss the effect of simultaneous implantation of artificial cavernous body and urethral sphincter for severe erectile dysfunction and urinary incontinence after traumatic posterior urethral stricture.Methods:A retrospective analysis was performed on 3 patients with traumatic posterior urethral stricture admitted to the Southern Theater General Hospital from January 2021 to December 2022, aged 42, 32, 28 years old, all of whom suffered pelvic fracture and posterior urethral stricture after trauma. Patient 2 were missing left lower limb and patient 3 were missing right lower limb, all of whom had dysuria. Preoperative cystourethrography indicated posterior urethral stricture with a length of 2, 2, 3 cm, respectively. No erectile response and severe erectile dysfunction were reported in penile nocturnal erectile function tests. Posterior urethral stricture was cured by end-to-end anastomosis surgery. After urethral stricture was cured, the nighttime erectile function test indicated severe erectile dysfunction and diagnosed erectile dysfunction and urinary incontinence. After 3 months of continuous administration of sildenafil and/or tadalafil, the erectile dysfunction did not improve, and the score of the international erectile function test was 1, 2, 2 points. Severe erectile dysfunction. The urine could not be controlled, the number of urine pads per day was 6, 6, 8, respectively, and pelvic floor rehabilitation training was adopted for urinary incontinence. 6 months later, urodynamic examination indicated severe stress incontinence, and the urine pad test was 30g, 32g, and 82g per hour. Patients were fully informed of the surgical risks before surgery. Simultaneous implantation of artificial penile cavernous body and artificial urethral sphincter were performed after full preoperative preparation: General anesthesia, supine frog position with transverse incision in upper scrotum, the urethra was separated and the artificial urethral sphincter cuff was easily inserted into the upper scrotum. Then the left and right sides of the penis cavernous sinus were dilated and the length of the cavernous body was measured. Suitable artificial penis cavernous body was implanted, water sacs were placed in the posterior pubic space and the anterior vesical space, and the tubes were connected. The erectile switch was placed under the scrotum, and the incision was closed after repeated testing of urine control and normal erectile function.Results:Three cases were successfully completed. The simultaneous implantation time of artificial cavernous body and artificial urethral sphincter was 270, 260, 240 min, respectively. The catheter was removed 1 week after surgery, and the erection switch was trained 2 weeks after surgery, and full erection was achieved after 1 week. The urine control switch was activated 6 weeks after surgery, and urine control was normal without urine pad. Following up for 12 to 18 months, 2 cases had normal erections and urinary control, 1 case had urethral corrosion 2 months after surgery, the original artificial sphincter was removed completely and a new artificial urethral sphincter was implanted in the same period, the operation was successful, and the follow-up was 1 year, urine control and erectile function returned to normal.Conclusions:For the severe erectile dysfunction and severe urinary incontinence after traumatic posterior urethral stricture, simultaneous implantation of artificial penile cavernous body and artificial urethral sphincter could be alternative choice.
RESUMEN
Objective:To evaluate the long-term efficacy of AdVance sling bulbar urethral suspension and artificial urethral sphincter (AUS) implantation in the treatment of moderate to severe male stress urinary incontinence.Methods:The clinical data of 12 male patients with urinary incontinence who underwent surgical treatment in Peking University People's Hospital from June 2011 to June 2017 were retrospectively analyzed. The median age was 75(64-80) years. There were 9 cases after radical prostatectomy and 3 cases after transurethral prostatectomy. Patients had a median history of urinary incontinence of 3(1-9) years, and needed an average of 8(5-10) pads per day. Among them, 5 patients had moderate urinary incontinence and 7 patients had severe urinary incontinence. All patients underwent urinary incontinence surgery for the first time. Among the 12 patients, 6 received AdVance sling ball urethral suspension (AdVance group), and 6 received AUS implantation (AUS group). The median age of the AdVance group was 72 (64-73) years. The median number of pads used daily was 6 (5-8) tablets. Urinary incontinence Quality of Life questionnaire (I-QOL) score was (15.0±5.4). Five patients had moderate urinary incontinence and one patient had severe urinary incontinence. In the AUS group, the median age was 78(76-80) years old, the median daily pad use was 8(6-10) tablets, and the I-QOL score was (16.7±5.1), all of which were severe urinary incontinence. The daily pad usage, I-QOL and postoperative complications were recorded at 1 and 5 years after operation.Results:All patients completed the operation successfully. The postoperative follow-up was 5-7 years (mean 5.5 years). In AdVance group, 1 patient with severe urinary incontinence had no significant improvement in postoperative symptoms at 1 year after operation. The other 5 patients showed significant improvement in urinary incontinence symptoms. In the AdVance group, the median number of pads used per day was 2.5 (1-10), and the I-QOL score was (75.0±28.1), which were all significantly improved compared with that before operation ( P<0.05). The median number of pads used per day in the AdVance group 5 years after operation was 2.5(1-10), and the I-QOL score was (78.3±29.3), which were significantly improved compared with those before operation (all P<0.01). In the AUS group, no pad was needed at 1 year after operation, which was significantly improved compared with that before operation ( P<0.01). Urethral erosion occurred in 2 cases 3 years after operation, and the AUS was removed. Urinary incontinence recurred and returned to the preoperative state without reoperation. The other 4 cases did not need to use the pad 5 years after operation. In AdVance group, 3 patients had perineal pain within 3 months after operation, which was related to activity and relieved spontaneously. No wound infection, urethral erosion and other complications occurred. Urethral erosion occurred in 3 cases in AUS group. Conclusions:AdVance sling ball urethral suspension is effective for patients with moderate stress urinary incontinence and has fewer complications. AUS implantation is effective for patients with severe male stress urinary incontinence. However, the long-term complications of this operation may affect the postoperative efficacy.
RESUMEN
Urinary incontinence is a relatively common and potentially disabling disease affecting the life quality of a patient. Many successful series in the treatment of incontinence by medical or surgical therapy using autologous materials have been reported. However, those who have structural abnormalities, injury around the urethra, and derangements in the nervous system could not be benefited by such treatments. In other countries, the artificial urethral sphincter, introduced in 1972, have achieved satisfactory results and then increased in use; but in Korea, it was not widely used because of many limitations and obstacles. Based on our ten-year experience with 10 cases of implantation of artificial urethral sphincter from 1987 to 1996, we tried to elucidate the present status, problems, and the possible ways of improvements of its use within this country. A total of ten male patients underwent implantations of the AMS Model 800 artificial urethral sphincter. Mean age was 34.5 (17-43) years. Mean follow-up was 4.2 (0.5-10) years. Two patients were spinal cord injury patients, 2 meningomyeloceles, and 6 posterior urethral injuries. Two patients had the prosthesis removed due to infection and cuff erosion. In the other 8 patients, 6 were dry (75.0 %) and 1 was improved (12.5 %) and 1 was wet (12.5 %). The revision rate was 20% (2/10) and overall improvement of incontinence was observed in 7 (87%) patients. The reasons for the low incidence of the implantation of artificial urinary sphincter in this country are as follows. According to the other reports, the most common application of artificial urinary sphincter in the west is in the post-prostatectomy incontinence accounting for about 60% of artificial urinary sphincter implantation whereas in this country, the majority of cases are patients who had trauma. Since radical prostatectomy has not been established well in the country (in the recent 4 years, totally only 53 cases were performed) and also the excellent performance of the transurethral surgery making the incidence of incontinence low, could be one of the reasons. In addition, the high price of the prosthesis over 4 million won and operation fee of 3 to 6 million won is a formidable burden to most patients. In the view of mechanical problem, the cuff size of the urethra in the oriental people is observed smaller than the western, and we must let the company prepare the cuff set of smaller size. In conclusion, if we solve those problems in our country, the artificial urethral sphincter is an effective device for treatment of urinary incontinence in patients who have failed more conservative modes of therapy.
